I will have to read further to understand his points better and whether I agree. Whenever an artist invokes "science" I tend to read skeptically.
There is no doubt that visual interest has a much greater impact on design today than 100 years ago, or even 25 years ago. In one thread a year or two back I talked about this era of design as the Age of Photography because we are all so self-conscious in that respect. And I have no doubt that my years of taking pictures of great golf courses, learning a bit from Brian Morgan about my own proclivities for composition, have impacted the look of the courses we build.
I also have strong feelings about certain other architects' work and their presentation style ... some who are among the most highly praised for their framing and aesthetic beauty are, to my eye, the most contrived looking of all. [A favorite story: years ago my wife and I toured a new course the day before its grand opening, and my wife noticed that someone had gone out and placed a single pine cone under each planted pine tree!]
However I have not agreed with the author's view in some of the examples cited. I do agree with the critique that added features have made courses more difficult to play, but some of the suggestions made in this first part seem to promote added water in areas where it's not essential to golf and would only punish the bad shots of the weaker player. Meanwhile, if you have a dramatic natural feature, I think it's crazy not to use it to its utmost, and find balance elsewhere.
